Description of problem:
With NFS mounts in an fstab it appears that NetworkManager and the 
autogenerated mount units get into a dependency loop which causes a number of 
important units to get discarded while trying to resolve the issue.

Version-Release number of selected component (if applicable):
Seen in FC16,17,18

How reproducible:
Every boot with NFS mounts in the fstab

Steps to Reproduce:
1. Try and boot a system with NFS mounts in the fstab.
2.
3.
  
Actual results:
Several units are deleted and never attempt to stop, several others fail 
because the root filesystem doesn't get remounted RW until other units time out.

Expected results:
System should come up, remount the root filesystem RW, mount NFS volumes in the 
fstab without dependency loops or units timing out.

This should be fixed by the latest f18 systemd update.
